Definitions
- the present invention relates to an air-tight container, and more particularly relates to an air-tight container comprising a sealing assembly over a lid, wherein the sealing assembly can be pressed down by a hand towards an air-releasing passage of the lid to release air from the air-tight container or allow air to enter into the air-tight container, and the air-tight container is sealed when the sealing assembly returns back to its original position when the hand is released from the sealing assembly.
- the moisture makes the food out of the quality when people use paper pack to pack the food as the paper pack cannot provide adequate packaging condition for storing food for a longer period, and therefore, paper pack is not suitable for preserving food.
- plastic or glass containers with lids available for storing food where the food can be conveniently put in or removed there-from.
- the plastic or glass containers do not provide effective preservation of food due to inadequate sealing and therefore moisture could penetrate into the containers.
- the present inventor makes a detailed study of related art to evaluate and consider, and uses years of experience in this field, and through several experiments, to create an air-tight container comprising a sealing assembly that can be disposed over a lid thereof, wherein the sealing assembly can be pressed down by a hand towards the air-releasing passage of the lid to release air from the air-tight container or allow air to enter into the air-tight container, and the air-tight container is sealed when the sealing assembly returns back to its original position when the hand is released from the sealing assembly.
- the lid of the air-tight container comprises an air-releasing passage, and a sealing assembly is disposed in the air-releasing passage of the lid.
- the sealing assembly comprises an axle protruding from a bottom side thereof, wherein an end portion of the axle comprises an indentation.
- a resilient element is disposed around the axle of the sealing assembly surrounding the axle of the sealing assembly.
- a sealing pad is disposed in the indentation of the axle.
- the sealing assembly is positioned in the air-releasing passage of the lid.
- the resilient element surrounding the axle of the sealing assembly is disposed between the top surface of the lid and the bottom side of the sealing assembly such that the resilient element will allow the sealing assembly to elastically move up and down in a vertical direction in the air-releasing passage of the lid.
- the lid is placed on top of the body of the air-tight container such that a plastic ring disposed in a indented groove at a bottom portion of the lid is adopted to tightly abut against the inner sidewalls of the air-tight container to substantially seal between the lid and the body of the air-tight container.
- the sealing assembly is a T-shaped structure and the sealing pad disposed in the indentation in the bottom end portion of the axle is adopted to seal between the interior of the lid of the air-tight container and the air-releasing passage of the lid.
- the air-releasing passage of the lid comprises an air-sealing hole on the top surface of the lid within the air-releasing passage in which the axle of the sealing assembly axially moves down under an external force applied thereto to release air from the interior of the air-tight container and also allow air to enter into the interior of the air-tight container, and return back to its original position when the external force is released to seal the interior of the air-tight container.

- Fig. 7 is a magnified view of section A of Fig. 6.
- Fig. 8 is a sectional side view showing an air-tight container according to an embodiment of the present invention.
- Fig. 9 is the sectional side view showing an air-tight container according to another embodiment of the present invention.
- the air-tight container comprises a body 1 having a receiving space 11 and a lid 2 for covering a top of the body 1.
- the lid 2 comprises an inlaying portion 21 having an indented groove 211.
- a plastic ring 22 is disposed in the indented groove 211, and the indented groove 211 is adapted for retaining the plastic ring 22.
- the inlaying portion 21 of the lid 2 comprises a buckling portion 212 having a sloped edge portion 2121 at a bottom flange thereof.
- a top portion of the lid 2 comprises an air-releasing passage 23 and an air-sealing hole 231 with a comparatively smaller diameter formed at a bottom of the air-releasing passage 23, and the air-sealing hole 231 comprises a sloped-edge face 232 at a bottom thereof.
- the air-releasing hole 231 communicates between the air-releasing passage 23 and the interior of the lid 2.
- a sealing assembly 3 comprises a T-shape sealing valve 31 having an axle 311 with smaller diameter protruding from a bottom thereof, wherein the axle 311 comprises an indentation 312 at a bottom end portion thereof.
- a sealing pad 33 is disposed in the indentation 312, and the indentation 312 is adapted for retaining the sealing pad 33 therein.
- the axle 311 is surrounded by a resilient element 32.
- the sealing assembly 3 is removably disposed in the air-releasing passage 23 of the lid 2, wherein the axle 311 is inserted into the air-sealing hole 231 and the resilient element 32 surrounding the axle 311 is disposed between the top surface of the lid 2 and the bottom side of the sealing assembly 3. Because the outer diameter of the sealing valve 31 of the sealing assembly 3 is smaller than that of the air-releasing passage 23, the sealing valve 31 can be moved up and down in a vertical direction within the air-releasing passage 23 and the axle 311 protruding from the bottom portion of the sealing valve 31 is inserted into the air-sealing hole 231 via the air-releasing passage 23.
- An outer diameter of the axle 311 is also smaller than that of the air-sealing hole 231, thus, gaps between the sealing valve 31 and the air-releasing passage 23, and between the axle 311 and the air-sealing hole 231 are formed. Accordingly, the air can pass through the gaps.
- the sealing valve 31 of the sealing assembly 3 can be pressed downwards with a hand, in doing so, the resilient element 32 surrounding the axle 311 get elastically compressed within the air-releasing passage 23 and the bottom end portion of the axle 311 of the sealing valve 31 gets out of air-sealing hole 231 and the sealing pad 33 retained in the indentation 312 of the axle 311 moves out through the air-sealing hole 231 over the sloped edge face 232 of the air-sealing hole 231.
- the air within the receiving space 11 of the body 1 is released through the air-releasing passage 23 via the air-sealing hole 231 of the lid 2. Consequently, the inlaying portion 21 of the lid 2 is firmly/tightly fit onto the receiving space 11 of the body 1. Furthermore, the buckling portion 212 positioned at the bottom flange of the inlaying portion 21 of the lid 2 contacts the inner sidewall of the receiving space 11 of the body 1 forcing the inlaying portion 21 of the lid 2 to elastically deform inwards. As the lid 2 is continuously pressed down, the plastic ring 22 disposed in the indented groove 211 of the inlaying portion 21 of the lid 2 elastically abuts against the inner sidewall of the receiving space 11 of the body 1 for position.
- the resilient element 32 of the sealing assembly 3 positioned above the lid 2 is returns to its original shape and position and thereby restore the sealing valve 31 to its original position.
- the sealing pad 33 of the axle 311 of the sealing valve 31 will retract and tightly abut between the sloped edge face 232 and the air-sealing hole 231 to seal the receiving space 11 of the body 1 and make the receiving space 11 in an air-tight condition.
- the receiving space 11 of the body 1 comprises a receiving groove 111 for receiving a chemical agent packet 4 therein, for example, desiccating agent, and a plate 5 is disposed over the chemical agent packet 4 so that food can be placed and stored in an air-tight condition within the receiving space 11 of the body 1 and can be separated from the chemical agent packet 4.
- a chemical agent packet 4 for example, desiccating agent
- a plate 5 is disposed over the chemical agent packet 4 so that food can be placed and stored in an air-tight condition within the receiving space 11 of the body 1 and can be separated from the chemical agent packet 4.
- the sealing valve 31 of the sealing assembly 3 is pressed down with a hand so that the resilient element 32 is compressed and the end portion of the axle 311 of the sealing valve 31 moves out of the air-sealing hole 231 and the sealing pad 33 gets out of the air-sealing hole 231 and the sloped edge face 232 at the same time.
- air from the atmosphere enters into the receiving space 11 via the air-releasing passage 23 and the air-sealing hole 231 of the lid 2 so that the pressure within the receiving space 11 of the body 1 and the outside is rendered same, and thus, the inlaying portion 21 of the lid 2 can be easily released from the receiving space 11 of the body 1.
- the hand is released from the sealing valve 31 so that the resilient element 32 surrounding the axle 311 will return to its original shape and position so that the axle 311 of the sealing valve 31 also returns back to its original position within the air-sealing hole 231 and thereby seal the air-sealing hole 231 such that the sealing pad 33 positioned at the bottom end portion of the axle 311 tightly abuts between the air-sealing hole 231 and the sloped edge face 232.
- the body 1 and the lid 2 are made of plastic material, and the lid 2 can be used to cover onto or release from the receiving space 11 of the body 1 repeatedly.
- the body 1 can be positioned at an angle, approximately 45°, with a hand pressing down the sealing assembly 3 above the lid 2 to let the air enter into the receiving space 11 of the body 1 and separate the lid 2 from the receiving space 11 of the body 1.
- the body 1 can be made of metallic material.
- a ring element 112 comprising an inner ring element 113 may be disposed around a top flange of the body 1.
- the plastic ring 22 within the indented groove 211 of the inlaying portion 21 of the lid 2 firms abuts against the inner surface of the inner ring element 113 of the body 1 to effectively seal the receiving space 11 of the body 1 in an air-tight condition.
- a inner protruded flange 114 protrudes from a top portion of the body 1 extending towards the inside, and a U-shaped sealing ring 115 is assembled to an inward indented flange 116 and a sealing circle 117 is disposed within the inward indented flange 116.
- the sealing ring 115 is assembled to the top flange of the body 1 and the sealing circle 117 tightly abuts against the inner protruded flange 114 to produce elastically deformation and sealed status and then the inlaying portion 21 of the lid 2 is fitted into the sealing ring 115 so that the buckling portion 212 of the inlaying portion 21 of the lid 2 contacts the innerside of the sealing ring 115 and thereby elastically deforming the inlaying portion 21. Furthermore, when the lid 2 is continuously fitted into the receiving space 11, the plastic ring 22 within the indented groove 211 of the inlaying portion 21 of the lid 2 is supported against the inner surface of the sealing ring 115 of the body 1, and elastically deforms to effectively seal the receiving space 11 of the body 1.
